ATTORNEY I Patented Aug. .20, i 1935 UNITED STATES PATENT OFFICE 7 CORNER BEAD William E. Peterson, Iron Mountain, Mich. Application September 5, 1934, Serial No.'742,810

V 4 Claims. (01. 72-121) The object of the present invention is to pro-- vide a bead for outside cornerswhich will accommodate expansion and contraction, will effectually hold the plaster, and will form a guide for a chamferedcorner. The invention is illustrated in the accompanying drawing and consists in certain novel features which will be hereinafter first fully described and then more particularly defined in the appended claims.

- In the drawing:

Figure 1' is a perspective view of the corner beadin position before plaster is applied thereto.

Figure 2 is a similar view showing the'completed corner.

Figure 3 is a completed corner.

The reference numeral ridge formedby the meeting edges of the wings. The wings, whenthe bead is in place, will lie against or extend'parallel with meeting sides of the post or scantling l, and at the remote edges of the wings, flanges 5 project outwardly therefrom. The flanges are. at right angles to the V respective wings and have openings 6 there- 2 through which are similar to the openings 4 and are staggered relative thereto. Along the outer free edge of each flange is formed a roll or hollow rib I from which a second flange 8 extends inwardly in divergent relation to the respective flanges 5, the flanges 8 preferably being formed with openings similar to the openings 4 and 6, and from the inner edges of the flanges 8 leaves '9 project to overlie the ends of the lathing. The leaves 9 are provided with openings l0 similar to the openings 4 and 6, and along their edges are smaller openings ll through which nails or other fastenings are driven to secure the bead to the lathing. v 7

After the bead is secured in place as stated, the. plaster I2 is applied over the lathing and the bead in the usual manner and will pass through the openings in the several members of the bead so that the bead will be completely embedded in the plaster andthe plaster will be stantially a right angle horizontal section through the l designates a vertical scantling or corner post to which lathing 2 is secured in the usual manner. My improved bead is pressed or stamped from a sheet metal blankto form a central plate havingdiverging longitudinal wings 3, 3 with openings 4 through the I inwardly from. the rolls in attractive finish will be provided and chipping ofthe corner will be avoided.

Having described my invention, what I claim is:

1. An outside corner bead including a central angle plate having diverging wings adapted to.

embrace an edge and extend along the meeting outer sides of a post or scantling, flanges on the edges of the wings projecting outwardly at subto the wings and adapted to extend substantially perpendicular to, said outer-faces of the post and to the lathing'upon which the bead is fixed, the flanges extending substantially at right angles to the flanges. v

'2. An outside corner bead including a central angle plate having diverging wings adapted to and end portions for l embrace an edge and-extend along the meeting outer sides of'a post or scantling, flanges on the edges of thewings projectingoutwardly at substantially a right angle to the wings and adapted 'to extend substantially perpendicular to said outer faces of the post and. to the lathing upon which the bead is fixed, hollow rolls along the free edges of the flanges, and end portions for 'the flanges extending substantially at right.

angles to the flanges.

3. An outside cornerbead including a central angle plate having'div'erging wings adapted to embrace an edge and extend along the meeting outer sides of a post or scantling, flanges on the edges of the wings projecting outwardly at substantially a right angle to the wings and adapted to extend substantially perpendicular. to said outer faces of the post and which the bead is fixed, hollow rolls along the free edges of the flanges, and flanges extending the first named flanges and terminating substantially in the plane of the edges of said diverging wings. r I

4. An outside corner bead including a central angle plate having diverging wings adapted'rto. embrace an edge and extend alongthe meeting outer sides of a post or scantling, flanges on .the edges of thewings projecting outwardly at substantially a right angle to the wings and adapted to extend substantially perpendicular to sai outer faces of the post and to the lathing upon which-the bead is fixed,hollow rolls along the free edges of the flanges, flanges extending inwardly from therolls in divergentrelation to the first named flanges and terminating substantially'in the plane of to the lathing upon theedges of said diverging wings, and leaves extendinglaterally' from the divergent relation to inner edges of the second named flanges disposed j r in the plane of said diverging wings and adapted 'to be secured to lathing.
